BaseTools: PatchCheck: Exclude bash scripts from CRLF check

Bash scripts require LF line endings to work.
PatchCheck.py checks that the files added in a patch have CRLF
line endings. It excludes files ending with the ".sh" extension
from this check.

Some bash script don't have a ".sh" extension. Most of them are
located in:
 - BaseTools/BinWrappers/PosixLike/
 - BaseTools/Bin/CYGWIN_NT-5.1-i686/

This patch excludes these folder plus BaseTools/BuildEnv from
this CRLF check.
